Repeated install failure

When attempting to install the AVG AntiVirus Free program, I receive the same issue at the end of the installation. It allows me to restart the computer (a HP Stream, if that helps), without any problems. It is only at the very end of the installation process that I receive an installation failed message, along with the following:
Error code: 0xC0070643
Description: Event exec_finished
I have tried to install the program repeatedly, including a full uninstall and reinstall. If it is relevant, the laptop came with McAfee, which I uninstalled before attempting to install AVG. I attempted to use the Customer Support form, choosing the Chat option, but the loading screen went on for over ten minutes. Can anyone help?

Hi Rajarajan et al,

It didn't work, I'm afraid. My OS is a 64-bit, for reference, and I received the exact same error code and description.

Hello Helen,

I have sent you an email with further instructions to be followed to get our additional support.
Please feel free to contact us for any further assistance. Thank you.

Hi Alan,

I hadn't when I posted, but I have since and I get the same problem, exact same error code and description.

Cheers!
